HB TCXX Rear Shock Tower (Low Mount) by Arrowmax AM-TCXX-68764  [AM-TCXX-68764]

Rear low-mount shock tower for HB TCXX

This Arrowmax AM-TCXX-68764 rear shock tower is an aftermarket, RC-scale replacement part produced for the HB TCXX platform. As a low-mount tower it locates the top of the rear shocks lower on the chassis, changing shock angle and mounting geometry compared with standard towers.

Fit and installation follow the HB TCXX mounting points, using the existing shock studs and mounting hardware from the stock tower. Check shock length and clearance after installation, and confirm upper ball stud alignment before final tightening. The part is intended as a direct-fit hop-up for builders who want a compact rear shock position without modifying other suspension pick-ups.

From a tuning perspective the low-mount arrangement affects roll centre and initial shock leverage, which can change rear grip, transient response, and body pitch under throttle and braking. Use the tower in combination with spring rate and shock oil adjustments to dial handling balance; small incremental changes to shock position and spring rate help isolate the tower’s effect during setup sessions.
